The Peugeot Metropolis 400 is a tilting three-wheeled scooter produced by Peugeot Motocycles.

The Metropolis 400 has - similar to the Piaggio MP3 - a separate suspension of the two front wheels with two wishbones.

The parallelogram suspension allows both front wheels to be guided in parallel.

In the summer, Peugeot Motorcycles and Dainese introduced the D-air system as an option "for all model variants of the Peugeot Metropolis".

[1] People whose license was issued before 19 January 2013, can drive the Metropolis 400 with a class B driving license, others with a class A2.
